(ores-a zii'I'he' present invention relates to nut installa- ,tions: and more particularly to the improvement of sheet metal .nut .members 1 adapted to be installed on and secured to sheetmetal or like support having an aperture near one edge thereof..

One of theobjects of the invention is the provision of a simplified nut member, which may be readily formed from a single piece of sheet material, and which may be positioned on one side of an apertured support, with portions thereof engaging on opposite sides of the support to securely hold the nut in place.

A further object of the invention is to provide a nut member of the above described type formed of readily bendable material so that a portion thereof may be manually bent around an edge of the support after the nut has been positioned with reference to the aperture. Y

Further objects to the invention are to improve generally nut fastehings of the above described types, as will be apparent to those skilled in the art from a consideration of the detailed description of the embodiments illustrated in the accompanying drawing, which is intended as purely illustrative of the invention.

In the drawing:

Fig. l is a top plan view of a nut installation embodying an improved nut according to themvention;

Fig. 2 is a bottom plan view thereof; a Fig. 3 is a detail vertical sectional view take on the line 3-3 of Fig. 1, the nut being shown in side elevation; l Fig. 4 is a plan view of the nut member per se, before being applied to a support;

Fig. 5 is a longitudinal sectional view of the nut taken on the line 5-'-5 of Fig. 4;

Fig. 6 is an enlarged transverse sectional view taken on the line 6-6 of Fig. 4;

Fig. 7 is a bottom plan view of one modified embodiment of the invention and Fig. 8 is a longitudinal sectional view of anothermodifled embodiment of the invention.

Referring to the illustrated embodiment of the invention'shown in the drawing, the nut member is primarily designed for attachment to a support I, having an aperture .-2 therein near one.

edge 3 thereof which aperture may be circular "in shape.

, The nut.member is preferably formed of a' single piece of sheet metal deformed toprovide a tubular barrel Ill preferably formed of opposed semi-cylindrical halves ll having lateralwings or extensions I! at their end edges, the latter ing barrel It].

being connected at their upper edges by folded portions t3) {halves I l L-andywings l 2 are ldisposed in .planes normal to thewbase, \OI' bQdXDI the nutportions l5 oflthe basel it aredis b the periphery qfthe barrel to provide upport- ,engaging surface torlimitmovement of the bar- I5 from the inner edge thereof, adapted to be positioned in and engage the wall of the aperture to limit shifting of the nut laterally rela-' tive to the aperture. One of: the depending extensions lfimay be formed with an outturned ioot' ll adapted to book under and engage the opposite face of the support, the foot I! being insertable in the aperture and hooked under the opposite face of the support by slightly tilting the nut on initial placement, as will be obvious.

The inner faces of the halves l I, forming the interior of the barrel, .are suitably tapped to provide screw-engaglng threads, as will be understood inthe art. i

One pair of the portions I5 of the base It is formed with lateral extensions iii of suflicient length to be folded over the adjacent edge 3 of the support I, to prevent rotation of the nut in the aperture 2. The extensions l8 may be folded back on the inner face of the support as shown in Figs. 2, 3 and 8, to cooperate with the portions IS in securing the nut against displacement from the aperture 2 of the support. If desired, the extensions may be connected by a bight portion l9,; see Figs. 2 and 4, which surrounds the aperture and provides for access of the screw to the nut. t

In use, the nut may be applied to the rear face of the support I in the manner described and the extensions bent against the forward face to hold the nut in position. An. apertured member 20 to be supported may then be positioned over the extensions l8 and the screw 2| passed through the aperture of the member 20 and threaded intoengagement with the screw-receiv- The entire installation is thus securely clamped together. 5

Instead of forming the nut of readily bendable soft sheet metal, as above described, it may be formed of somewhat stifler resilient metal and the extensions l8 formed with a laterally offset hooked portion 22 for snap fastener engagement with the'adjacent edge 3 of the support, as illustrated in Fig. 8.
